Narrative:

We had just landed runway 26R atl, and upon clearing the runway at the first high speed turnoff (taxiway B5) we were told to hold short of runway 26L at taxiway B2. B2 is next to B4, and B4 is not, repeat not, marked. I confused B4 for B2 and pulled up to B4. Controller told us to continue up to B4 on bravo taxiway. I never got near runway 26L and no other aircraft were close so there was never a conflict. Technically, I did not comply with the ATC instructions but the violation was not intentional because B4 is not marked so as to be able to see the signs as you pull off the runway.
